heat from the fire, sound from
the police siren (forms of
energy); Matter: picture of any
solid, liquid or gaseous
substance. Let the students
cite the differences between
the two and write them on the
board.
Show to the students a glass
of water. Obtain ideas or

IV. LEARNING TASKS
ELICIT
In Grade 7, students learned
about the periodic table. Let
them recall some common
elements found in the periodic
table.
Show to the class a video from
YouTube entitled: History of
Periodic Table
Animation
(cite provided in Learning
Resources under additional
materials)
Using the periodic table, The
teacher will mention an
element (e.g. Calcium).
Let them look in what column and
row it is located or you may do
otherwise (students will look for
the name, teacher will mention
the row and column)
Let the students watch the video
The NEW Periodic Table Song
(Updated) on YouTube.
materials)
ENGAGE
Ask:
How was your seating
arrangement done?
(possible answers:
alphabetically, height, gender)
Who were the people mentioned
in the video? (Write their
answers on the
board for later discussion)
Let the students take hold of their
periodic table and ask them of the
possible ways how those
elements were arranged.
Were they arranged
alphabetically? randomly? Or
other possible arrangements?
After watching, let them cite some
names of elements they have
seen and where they can
commonly be found or used.
Example: Silver-spoon
Essential Question:
How did the periodic table develop?
Essential Question:
How were the elements in the periodic table arranged?

who grouped elements in three
with similar properties.
2. This arrangement was
proposed by Newlands.

I. OBJECTIVES
Content Standard
The Learners demonstrate an understanding of: the periodic table of elements as an organizing
tool to determine the chemical properties of elements
Learning Competency
trace the development of the
periodic table from observations
based on similarities in properties
of elements
The Learners should be able to: use the periodic table to predict the
chemical behavior of an element.
Code: S8MT-IIIa-b-8 S8MT-IIIc-d-9
DAILY TASK Make an Element Brochure Compare the reactivity of metals in acid solution

ENGAGE
Ask the students how rusting
of objects affect people.
You may ask the following
questions: (to be posted
before watching the video)
1. What is rust?
2. What are the factors
involved for rusting to
occur?

happen?
4. In what condition
does rusting process
is hastened?

EXPLORE
Students will be tasked to create an
attractive brochure presenting
informative details about the
assigned element by pair. The
brochure will be a tri-fold 8.5 x 13
